ELECTRIC PROGRAM-CLOCK.

SPECIFICATION forming part of Letters Patent No. 683,257, datedSeptember 24, 1901.

Application filed April 1, 1901. Serial no 53 919, (NO model.)

To all whom it may concern:

Be it known that I, BENJAMIN DUBINSKI, a citizen of the United States,residing in San Antonio, in the county of Bexar and State of Texas, haveinvented certain new and useful Improvements in Electric Time-ReminderClocks, of which the following is a full, clear,

and exact description, reference being had to the accompanying drawings,forming part of this specification.

My invention relates to that class of clocks designed for service infurnishing notice to the user of acts to be performed atpreviouslyspecified times or periods of the day.

The invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a View in front elevation of my improved clock. Fig. II is arear elevation. Fig. III is a detail perspective view of the revolvingcontact-carrying arm. Fig. IV is a longitudinal sectional view taken onthe line IV IV, Fig. III. Fig. V is a sectional view taken on line V V,Fig. I, showing one of the card-holders in elevation. Fig. V1 is adetail perspective view of one of the card-holders. Figs. VII and VIIIare views illustrating modifications of the springs connected to thecard-holders.

1 designates the back of a clock-face provided with a dial 2 andsurrounded by a rim 3. 4 is a glass door that incloses the dial 2.

The rim 3 is surrounded by a hollow metallic ring 5, on the front andrear faces of which are numerals indicating the hours of the day andfractional parts of the hours. The numerals mentioned may designate thehours from one to twelve or from one to twenty-four, as may be desired,and the figures on the dial of the clock may also designate the hoursfrom one to twenty-four instead of merely from one to twelve, as shown.

6 designates a casing inclosing the clockmovement, the said casing beingsuitably afiixed to the back 1 of the clock-face.

The hollow ring 5, encircling the rim 3, is apertured at the location ofeach of the numerals on the rear face of said ring, and located in saidapertures are a series of cardholders that extend from the exterior ofthe ring therethrough to the interior of the clock.

The card-holders are provided with heads 7, consisting of three prongs 8and 9 of waving form, the two outer prongs 8 being bent in correspondingdirection and the intermediate prong 9 being bent in opposing direction,so that when a card is slipped into the head 7 it will be grippedbetween the two prongs 8 on one side and the prong 9 on the oppositeside, and thereby be held firmly to the holder. Each card-holder has ashank 10, provided with an aperture 11 and a notch 12. Beside the notch12 is a tongue 13, that is bent at an angle to the main body of theshank.

14 is a spring surrounding the shank 10 of the card-holder within thehollow ring 5, said spring being adapted to rest at one end against theinner face of the outer wall of the ring and being connected to theshank 10 by passing its inner end through the aperture 11 in said shank.The tendency of the springs 14 is to carry the card-holders inwardly.When said card-holders are in their outermost positions, they are heldby engagement with the inner wall of the hollow ring 5 by reason of thenotches 12 being moved to said inner wall and the inner ends of theshanks being swung laterally, as illustrated in Fig. V, so that theshouldered edges of said shanks at the location of the notches will restagainst the inner wall of the ring 5. When the inner ends of the shanks10 of the card-holders are swung so as to move the notches 12 out ofengagement with the ring 5, the springs 14 carry the card-holdersinwardly, as illustrated by dotted lines in Fig. V, thereby projectingthe inner ends of the shanks beyond the inner face of the ring 5. Thetongues 13 serve as stops to limit the outward movement of thecardholders and prevent their extraction.

l5 designates an alarm-bell that is connected by a wire 16 to a battery17, and also connected by a wire 18 to a binding-post 19, fixed to thering 5.

20 is a wire leading from the battery 17 to a binding-post 21, alsofixed to the ring 5. The binding-post 19 is connected to theclockmovement casin g 6 by a circuit-wire 22. The wire 20 conductscurrent from the battery to the ring 5 through the binding-post 21.

23 designates a contact-carrying arm fixed to and carried by the arbor24 of the hour hand of the clock. The contact-carryin g arm 23 isprovided at one end with a counterbalance 25.

26 is a slotted slide adj ustably connected to the contact-carrying arm23 by bolts 27, that are seated in the arm 23 and pass through the slotsin said slide.

28 is a contact pivoted to the slide 26 by a pin 29, the said pin beingsurrounded by 'a spring 30, that bears against the head of the pin andagainst the shank of said contact and serves to hold the contactnormally in alinement with the slide 26 and also to return the contactto said normal position after it has been swung to one side, as willhereinafter appear.

In the practical use of the clock cards A, containing information as tothe matter requiring attention at a specified time, are inserted in theheads 7 of the card-holders in the manner stated. The card-holders arenormally at rest in their outer positions, as

seen in Fig. V; but when a card is placedtherein the holder is moved totrip its shank from engagement with the ring 5 and permit the spring 14to carry the shank inwardly into a more projected position beyond theinner face of said ring. As the contact-carrying arm 23 moves aroundunder the action of the clock-movement the pivoted contact 28 is carriedto the inwardly-projected shank of the card-holder that has been movedinwardly, and the engagement of the pivoted contact with said shankefiects the completion of the circuit from the battery over the wires16, 18, and 22 to the movement-casing '6 and from said casing over thecontact-carrying arm 23 and pivoted contact 28 through the cardholder tothe ring 5 and back to the battery over the wire 20. The circuit is thuscompleted, causing the bell 15 to be rung, calling attention to the actto be performed at the time indicated at the location of the cardholderprojected.

In Figs. VII and VIII, I have shown modifications of the springs bywhich the cardholders are projected during the day. In

Fig. VII the shank 10 of the card-holder is provided with a notch thatreceives a bowspring 14?, that is-fixed to the ring 5". In

'Fig. VIII the shank 10 of the card-holder is its individual space, andthereby designates the hours or fractional part of the hour of the dayat which the alarm may be sounded.

I claim as my invention F 1. In a reminder-clock, the combinationl witha clock-movement of a casing having circuit connection with an electricbell, a ring I having circuit connection with said bell, a sei ries ofcard-holders loosely arranged in said ring and adapted to be projectedinwardly in said ring, an arm carried by said clock-movement, a slottedslide adj ustably connected to said arm, a contact having arearwardly-projecting perforated lug at right angles thereto, a pinpivotably securing the arm and lug together, and a spring coiled aroundthe said pin, the ends of said-spring being rigidly secured in said lugand head of the pin respectively whereby the contact is held normally inline with the slide, said contact being adapted to engage the inner endsof said card- I holders, substantially as described.

2. In a reminderclock, the combination with a clock-movement and acontact-arm carried by said movement, an apertured ring, a series ofspring-actuated card-holdersmounted in said ring, said card-holderscomprising notched shanks adapted for engagement with said ring, andouter heads having waving prongs arranged to receive cards,substantially as and for the purpose set forth.

BENJAMIN DUBINSKI.
